Q
What is full depth cold in-place recycling technology?
Full depth cold in-place recycling is a pavement rehabilitation technology developed on the basis of road mixing technology. It recycles and reuses materials from old asphalt pavement and base course directly on-site without heating, making it one of the most widely used in-place recycling technologies available today.
Q
What types of roads is this technology suitable for?
This technology is primarily suitable for the rehabilitation, upgrading, and reconstruction of severely distressed asphalt pavements on second and third grade highways, general rural roads, and roads requiring base course reinforcement or low-grade road upgrades.
Q
How does this technology reduce construction costs?
By recycling and reusing existing pavement and base course materials directly on-site, the need for transporting new materials and disposing of old materials is greatly reduced. This significantly lowers both material transportation costs and overall project time.
Q
Is full depth cold in-place recycling environmentally friendly?
Yes. Because the process is carried out cold (without heating), it consumes less energy and produces lower emissions compared to traditional hot-mix asphalt methods. The on-site reuse of materials also minimizes waste and reduces the environmental impact of construction.
Q
What surface treatments are required after cold in-place recycling on rural roads?
For general rural road surface renovation using this technology, an upper sealing layer must be applied after recycling. Suitable treatments include slurry seal, chip seal, or micro surfacing to ensure proper surface performance and durability.
Q
Can recycled materials be reused as a structural layer?
Yes. The renewed materials produced through full depth cold in-place recycling can be effectively reused as the base course of asphalt pavement or as the under layer for roads with low traffic volume, providing a cost-effective and sustainable structural solution.
